Application filed April 11, 1912. Serial No. 689,954.

To all w/iom i t may concern:

Be it known that I, GIsr. H.1'HUMIIIREX, a citizen of the United States, residing at WVilkinsburg, in the county' of Allegheny transmitted tothe vehicle body when the vehicle passes over uneven surfaces is minimized, and the vibrations that follow the shock usually when the vehicle is mounted upon spring supports is entirely eliminated, and in addition to these advantages the beauty of the car frame is enhanced. I

accomplish these several objects by means of the device more specifically described, ref

erence being had to the accompanying drawings forming part hcreof, in'which Figure 1 is aside elevation of an automobile with my improvement applied tl 1ere-.

to. Fig. 2 is a longitudinal sectional view through the keeper within which the rear end of the pivotally mounted shock absorbing bar is loosely received.- Fig. 3 is an end view of the keeper. Fig. 4. is a side elevation of the keeper. Fig. 5 is a view similar to Fig. 2, showing a modified construction in which but a single spring is employed, and Figs 6 .is a front elevation of one side of therunning gear.

Referringto said drawings, 1 is the side rail of the frame of the car.

2, 2 are axletrees whereon are mounted the car frame and body. I

'4 is what I term a shock receiving and transmission bar, the forward end of which is pivotally secured at a point above the horizontal plane of the side rail of the frame, the forward end of said bar being preferably curved from its pivotal conncc tion to a point to which it is secured to the axletree 2, 2, the extension of saidbars beyond this point being preferably slightly upwardly inclined, the free end thereof ertend ng frea-rwardly of the axletrees and passing beneath a spring or springs 5, 5, or

. other re ilient members, which are mounted "on: the brackets 6. The said brackets comprise two plates or pieces a, 7), bolted or 0th erwise' secured upon the side rails of the car near the front and, at the rear of the same. both of said'brackets being arranged rearwardly of the wheels. The free ends of said bars 4, 4 maybe curved as shown on the drawing to add finish to the structure.

7 is a rod secured in the curved front end of the car frame and-extending transversely I of the same, to' which the license plate 8 may be suspended if desirable.

The operation of my device is as follows: The'shock or jolt occasioned by the passing over uneven surfaces is transmittedapprqxh mately in a line indicated by the arrow; Thiswill have a tendency to throw the wheel contacting with the obstruction in the direction indicated by the arrow, thus-transmitting the shock to the bars 4, the upward movement occasioned-by the shockswinging the bars on their pivotal connections, thus transmitting the shock to the springs or other resilient member actingthereon and compressing the same. In the form of device two springs may be utilized as indicated in Fig. 2 .of the drawings. The shock if very great might compress one of the springs almost completely. The other spring, however, being shorter, acts as a reinforcing 5 receives andloosely engages the positioning-and guiding stud 9 which terminates in a rubber nose 10, while the lower end-o'f the spring receives and is positioned by a rubber stud 11, This rubber stud 11 is adapted to engage the rubber nose 10 of the upper positioning stud 9 when both of thc'springs are compressed to the maximum extent. After the car passes over the-obstruction and in coming to normal position swings upon its pivotal connection with the bars t the distention of the springs forces the free spring. The upper end of the short spring.

ends of the bars into normal position, thus bringing the car to normal position upon the pneumatic wheels and preventing the vibrat-ion which always accompanies a shock when the car body is suspended upon spring supports of: the ordinary type. It is noted frame are carried up in a curved line above the normal horizontal line thereof and'that the pivotal connections of the bars 4 secured upon the rear axletrec are likewise carried up above the normal horizontal lineof the side rail. This construction permits a very ready upward movement of the axletrees upon the pivotal connections securing the frame upon said bars. The advantages of that the forward ends ofthe'side railsof the I my construction will be" obvious to those skilled in the art to which itappertains. It

.to the wheel.

may further be pointed out thatvwhen the wheel strikes an obstruction the shock ab sorbing bar 4- is swung rearwardly about its pivotal 'connection'with the main frame $01 as to carry the wheel rearwardly'and simulmucous-1y permit the body of the vehicle to travel forward a slight'amount with respect Assoon as the obstruction has been passed, the. wheel and vehicle body will again resume normal position,'althongh the relative forward movement of the 've* hicle body with respectto the-wheel is of.-

- very great. advantage inabsorbing the shock.

I if desired to minimize still more the t'endency tofvibration in the. structure in coming toe-normal position after .shock', Qfriction disks may be interposed between the bars 4 and. the bearings at the pivotal connection thereof.-

Having described my invention, what I claim and desire to secure by LettersjPatent .lsi 1. In adevice ofthe character described,
